14<H2>Description</H2>
15<P>
16This is a list of the values that can be specified within RSF files for <CODE>PublicSaveDataSize</CODE> and <CODE>PrivateSaveDataSize</CODE>.
17</P>
18<P>
19With NAND applications, you must specify the size of the save data region within the RSF file. Below is a list of the values that can be specified as the sizes for save data regions, along with the sizes that can actually be used in applications when each value is specified.
20</P>
21<P>
22The save data region of NAND applications are managed using a FAT file system. Because it is necessary to maintain internal information for file names and directories, some additional amount of memory is required in addition to the actual file size. For information on the TWL FAT file system, see <a href="../fs/overview/about_Archive.html#FAT">FS Library Overview</a>. To determine the size that files in the save data region can actually consume, use the <a href="../fs/archive/FS_HasEnoughSpaceToCreateFile.html"><CODE>FS_HasEnoughSpaceToCreateFile</CODE></a> function.
23</P>

25<H2>How to View This Table</H2>

27<P>
28The meanings of each column are shown below.

31<table class="table">
32<tr><th nowrap="1">Specified Value
33	<td>Shows the values that can be specified within RSF files for <CODE>PublicSaveDataSize</CODE> and <CODE>PrivateSaveDataSize</CODE>.
34<tr><th nowrap="1">Region Size
35	<td>The value of <CODE>totalSize</CODE> that can be obtained with the <a href="../fs/archive/FS_GetArchiveResource.html"><CODE>FS_GetArchiveResource</CODE></a> function when the corresponding &quot;Specified Value&quot; is chosen. This value indicates the maximum size of the file that can be created.
36<tr><th nowrap="1">Maximum Number of Files
37	<td>The maximum total number of files and directories that can be created directly under the root directory when the corresponding &quot;Specified Value&quot; is chosen. The total number of files and directories that can be created immediately under the root directory depends on the length of the names, so the practical maximum is this value or less.
38<tr><th nowrap="1">Cluster Size
39	<td>The units used for the size of the region when the corresponding &quot;Specified Value&quot; is chosen. For example, if the cluster size is 512 bytes, both a 1-byte file and a 512-byte file consume a region of 512 bytes each. Likewise, a 513-byte file and a 1024-byte file both consume a region of 1024 bytes.
